Well the handheld iterations of the series have always been fantastic!!! I loathed NSMB on Wii. It was just terrible!!!!! Clearly it was made to appeal to those dammed casual gamers. Heaven forbid they play a game that actually challenges them.
Had NSMB Wii been a launch title im sure it would have added signifigant fuel to the Wii fire. I however would have been just as dissapointed with it regardless of when it launched
